Long Short Term Memory (LSTM) is a Recurrent Neural Network (RNN) architecture designed to better model temporal sequences (e.g. audio, sentences, video) and long range dependencies than conventional RNNs [1]. There is a lot of excitement in the machine …
Using the libraries pkmFFT and pkm::Mat, you can very easily perform a highly optimized short time fourier transform (STFT) with direct access to a floating-point based object.

Apple’s Accelerate Framework can really speed up your code without thinking too much. And it will also run on an iPhone. Even still, I did bang my head a few times trying to get a straightforward Real FFT and IFFT …
